Abstract

Learning to play a musical instrument is usually tackle with the help of a music teacher. For learning purposes there already exist computer programs and applications that help the user in learning process. Many programs have a disadvantage of not showing the correct finger order while playing an instrument. In this thesis work we developed an application for an Apple iPad tablet, which teaches the user how to play the bass notes on the diatonic accordion. The presented information is based on the techonolgy called augmented reality. First are presented examples of augmented reality applications in various fields of use. Followed by a presentation of the programs and tools used in the development. In the following we focus on the problem with detection of the keys on the diatonic accordion. Among available technologies the marker detection algorithm based on open source library for coumputer vision OpenCV is being used. Then the outline of augmented reality is presented. Moving along the thesis work presents the advantages of MIDI protocol for saving all the data needed in the application. Before the completion of the thesis work reader will get to know the possible improvements of final implemented application.
